According to a rep for the 18-year-old actress/singer, Demi “left her tour early this weekend in order to seek medical treatment for emotional and physical issues she has dealt with for some time.”

The Sonny with a Chance star "has decided to take personal responsibility for her actions and seek help,” the statement read. “Demi and her family ask that the media please respect their privacy during this difficult time. She regrets not being able to finish her tour, but is looking forward to getting back to work in the near future."
